Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component supply apparatus in which, for example, a large number of tape cassettes are slidably mounted side by side to supply chip parts and the like to a mounter body. The present invention relates to a cutter mechanism for cutting a tape waste after being taken out.

[0002]

2. Description of the Related Art An electronic component supply apparatus of this type includes, for example, a cassette base on which a large number of tape cassettes arranged side by side are mounted, and a machine base on which the cassette base is slidably mounted in its longitudinal direction. The cassette base is moved so that a desired tape cassette faces the mounter main body.

Further, a technique has been developed in which the cassette base is moved by a linear motor incorporated between the cassette base and the machine base to enable high-speed movement (Japanese Patent Laid-Open No. 61-239696).

[0004] This linear motor comprises a pair of stators fixed to a machine base, and a mover suspended from the lower surface of a cassette base. The pair of stators is arranged so as to sandwich the mover from both sides thereof. I have. The stator is configured by arranging a large number of magnets in the longitudinal direction of the machine base, and the mover is configured by winding an exciting coil around a magnetic structure.

As described above, in a component supply apparatus in which a cassette base on which a large number of tape cassettes are mounted is horizontally moved to move a desired tape cassette to a component supply position, electronic components are moved while the cassette base is horizontally moved. It was necessary to cut the tape appropriately so as not to disturb the tape waste after being taken out. Therefore, the tape waste of the tape cassette that has reached the component supply position is cut by the cutter mechanism. Note that all the tape cassette bodies may be provided with a cutter mechanism, but this is disadvantageous in cost.

[0006]

However, the configuration described above in which the cassette base is moved horizontally and the tape debris of the tape cassette reaching the component supply position is cut by the cutter mechanism has the following problems. .

That is, as the mounter speeds up, the operation timing of each unit overlaps. For example, when the horizontal movement of the cassette base and the cutting operation by the cutter mechanism overlap, when the horizontal movement of the cassette base is stopped as shown in FIG. 11 (timing T1 shown in FIG. 11), the cutter blade of the cutter mechanism is stopped. (The upper blade and the lower blade) must have a space (space between the upper blade and the lower blade: h (see FIG. 10)) enough to allow tape waste to enter. Then, after the cutter blade is closed and the tape waste is cut, the cutter blade starts to open again to secure the space (h), and then the cassette base is horizontally moved (timing T2 shown in FIG. 11).

At this time, if the horizontal movement cycle of the cassette base is determined, the only option is to adjust the opening and closing operation of the cutter blade. That is, the opening and closing operation of the cutter blade is operated at high speed. However, in this case, the vibration and the sound at the time of cutting the tape become too loud, and the practicality is low.

Therefore, according to the present invention, even when the horizontal movement cycle of the cassette base is determined, the electronic component supply device enables a stable tape cutting operation without extremely opening / closing the cutter blade at an extremely high speed. The purpose is to provide.

And a mounting system 4 that mounts the electronic component on the substrate B. The supply system 3 includes an electronic component supply device (3).

The apparatus main body 2 includes an index unit 6 serving as a main body of a drive system, a rotary table 7 connected to the index unit 6, and a plurality (1) mounted on an outer peripheral portion of the rotary table 7.
2) mounting heads 8 are provided.

When the rotary table 7 rotates intermittently, the suction nozzle 9 mounted on each mounting head 8 faces the supply system 3 and the mounting system 4 as appropriate, and after sucking the electronic component A supplied from the supply system 3, the mounting system 4
, And is mounted on the substrate B introduced into the mounting system 4.

The electronic component supply device 3 constituting the supply system includes:
A machine base 11 long in the front-rear direction and four slide bases (unit bases) 1 slidably mounted on the machine base 11
2, a large number of tape cassettes (component supply units) 13 detachably mounted on each slide base 12,
1 and a linear motor 14 incorporated between each slide base 12. Four slide bases 12
Are arranged before and after the machine base 11 as a set of the two,
Two sets of tape cassettes 13 are alternately made to face the apparatus main body 2 via the slide bases 12 and 12 of each set. That is, while the two slide bases 12, 12 each carrying a large number of tape cassettes 13 move (slide) to the position of the apparatus main body 2 and perform the component supply operation, the other slide base 12, which is at the home (origin) position. On the two slide bases 12 and 12, the exchange operation of the tape cassette 13 is performed for the next operation.

As shown in FIGS. 2 and 3, each of the tape cassettes 13 is formed to be thin, and a plurality of thinly formed tape cassettes 13 are mounted side by side on the upper surface of the slide base 12 with a narrow gap. Have been. In this case, each tape cassette 13 is positioned on the upper surface of the slide base 12, and is detachably mounted by operating a lever. The mounting head 8 (suction nozzle 9) of the apparatus main body 2 faces the tip of the tape cassette 13 mounted on the slide base 12 in order to suck the electronic component A. A carrier tape C loaded with electronic components A at a predetermined pitch is mounted on the tape cassette 13 in a state wound around a tape reel 16, and the electronic component A is mounted on a carrier unwound from the tape reel 16. The suction nozzle 9 sucks the tape C at any time.

The slide base 12 is connected to the left and right joining members 2.
It comprises an upper base block 22 and a lower slide block 23, which are positioned and fixed via 1A and 21b. The tape cassette 13 is mounted on the upper surface of the base block 22, and a pair of left and right sliders 24A and 24b is provided on the lower surface of the slide block 23. The base block 22 includes a horizontal portion 26 and an inclined portion 27.
The inclined portion 27 is disposed at a position where the tape reel 16 has escaped from the tape cassette 13 mounted on the horizontal portion 27.

The slide block 23 is formed integrally with the upper horizontal portion 29, the vertical portion 30, and the lower horizontal portion 31 so as to have a crank-shaped cross section. A part 32 is formed. The upper horizontal portion 29 supports the horizontal portion 26 of the base block 22 via one joining member 21A, and the rib portion 32 supports the inclined portion 2 of the base block 22 via the other joining member 21b.
7 is supported. The first slider 24A is fixed to the lower surface of the outer end of the upper horizontal portion 29, and the second slider 24A is fixed to the lower surface of the outer end of the lower horizontal portion 31.
b is fixed.

Further, on the lower surface of the outer end of the upper horizontal portion 29, an optical sensor 36 constituting a linear encoder 35 is vertically provided between the upper horizontal portion 29 and the scale 34 attached to the machine base 11. An end of a cable carrier 38 that supplies a control signal and electric power to the linear motor 14 via a bracket 37 is connected to the upper surface of the outer end of the lower horizontal portion 31. Reference numeral 39 in the figure denotes a photo interrupter, and this photo interrupter 39 detects when each slide base 12 overruns the home (origin return) position.

The gantry 11 is composed of a gantry body 41 and a vertical block 42.
A first slide rail 43A with which the first slider 24A is engaged is attached.
A second slide rail 43b with which the second slider 24b engages is attached. In addition, the vertical block 42
An upper magnet base 44 extending horizontally is attached to the upper surface of the main body 41. A lower magnet base 45 is attached to the upper surface of the main body 41 in correspondence with the upper magnet base 44.

The linear motor 14 includes a pair of upper and lower stators 47A and 47b fixed to the machine base 11, and a movable element 48 fixed to the slide base 12. Of the pair of upper and lower stators 47A and 47b, the upper stator 47A is fixed downward on the lower surface of the upper magnet base 44, and the lower stator 47b is fixed upward on the upper surface of the lower magnet base 45. On the other hand, the mover 48 has substantially the same length as the slide base 12 and
3 is fixed to the side surface of the vertical portion 30. In this state,
The upper surface of the mover 48 faces the upper stator 47A, and the lower surface faces the lower stator 47b with a gap (air gap). That is, the mover 48 and the upper and lower stators 47A, 4
7b is vertically opposed, and constitutes the linear motor 14 as a whole.

The mover 48 fixed to each slide block 23 is formed by winding an exciting coil around a magnetic structure (not shown), while the upper and lower stators 47A, 47b are arranged.
As shown in FIG. 4, a large number of magnets 49 are arranged in the longitudinal direction of the machine base (the upper and lower magnet bases 44 and 45) 11 in a row. In this case, a large number of magnets 49 are arranged at equal intervals with a minute gap 50 therebetween, and a resin 51 is molded in each gap 50. That is, the gaps 50 of the many magnets 49 are molded with the resin 51 so that the surfaces of the upper and lower stators 47A and 47b are flush with each other.

As described above, according to this embodiment, the mover 48 and the upper and lower stators 47 in the linear motor 14 are used.
A and 47b are disposed so as to face up and down, so that the mover 48 and the upper and lower stators 47A and 47b are covered by the upper magnet base 44 from above.
For this reason, even if the electronic component A or indoor dust that is repelled due to a suction error falls to the upper side of the linear motor 14, the upper magnet base 44 functions as an eave that covers the linear motor 14, and particularly the upper and lower Each stator 47A, 47b
It is possible to prevent the electronic component A and dust from adsorbing or adhering.

Therefore, the electronic components A and the like are fixed to the respective stators 47.
It is possible to reliably prevent the linear motor 14 from being hindered from being caught between the movable members A and 47b and the mover 48. As described above, the upper magnet base 44 also serves as a dust-proof member, and the distal end thereof is connected to the upper stator 47A.
It is preferable that the projections extend sufficiently outward. In particular, it is more preferable that the upper magnet base 44 protrudes outward to the extent that the magnetic force is saturated. Further, the upper magnet base 44 may be formed integrally with the vertical block 42.

On the other hand, since the gaps 50 between the magnets 49 of the upper and lower stators 47A, 47b are molded with the resin 51, the electronic components A, dust and the like that have fallen into the gaps 50 do not accumulate. However, it is possible to prevent the electronic component A or the like from getting stuck between the stators 47A and 47b and the mover 48 beforehand. It is preferable that the mold resin 51 thinly covers not only the gaps 50 of the magnet 49 but also the surfaces of the upper and lower stators 47A and 47b.

Next, a cutter mechanism 60 (particularly in FIG. 1), which is a feature of the present invention, cuts off the tape scraps from which the electronic components A of the tape cassette 13 reached the component supply position by the horizontal movement of the slide base 12. 5) will be described in comparison with a conventional configuration (in particular, see FIG. 10).

The present inventor has a configuration in which the horizontal movement of the slide base 12 and the tape cutting operation by the cutter mechanism 60 are overlapped, and the opening and closing operation of the cutter blade is performed when the horizontal movement cycle of the slide base 12 is determined. We have invented a technology that can cut tape without operating at extremely high speed.

That is, the inventor paid attention to the conventional cutter mechanism 70 shown in FIG. 10, particularly the lower blade shape. The conventional cutter mechanism 70 is a mechanism that cuts a tape scrap (not shown) between a fixed upper blade 71 and a lower blade 73 that swings about a shaft 72 as a fulcrum.

A dimension L1 shown in FIG. 10 is a stroke when the lower blade 73 is swung (moved in the direction of ⇔) around the shaft 72 as a fulcrum, and a dimension h is as described above.
Is the required distance between the upper blade 71 and the lower blade 73 when the horizontal movement stops.

FIG. 11 shows the conventional cutter mechanism 70.
Horizontal movement of slide base 12 and cutter mechanism 7
0 is a diagram for explaining an overlapping state of the tape cutting operation by 0, as can be seen from this figure, when the slide base 12 stops moving horizontally (timing T1),
In order to secure a necessary interval h between the upper blade 71 and the lower blade 73, the opening and closing movement of the upper blade 71 and the lower blade 73 had to be performed at high speed. That is, of all the strokes L1 described above,
Stroke L3 (shorter than stroke L2 described later)
The above-mentioned interval h is reached only by swinging the lens. Therefore, it is necessary to delay the start (timing tb) of the closing operation of the lower blade 73 (after the timing ta described later). Therefore, in the conventional cutter mechanism 70, the opening and closing movement cycle of the cutter blade becomes steeper as shown in FIG. 11 as compared with the opening and closing movement cycle of the cutter blade of the present invention shown in FIG. And the problem that the sound became loud occurred.

Therefore, the present inventor has responded to the above problem by improving the shape of the lower blade.

That is, when the lower blade is swung by the same stroke (dimension L1), the timing of contact with the tape scraps is delayed as much as possible (stroke L2> stroke L3 shown in FIG. 5), so that the opening and closing movement of the cutter blade is performed. We thought of eliminating the need to do it at high speed.

Hereinafter, the configuration of the cutter mechanism 60 of the present invention will be described.

In FIG. 5, the cutter mechanism 60 is
As in the case of the conventional cutter mechanism 70, tape scraps (not shown) are formed by the fixed upper blade 61 and the lower blade 63 that swings about the shaft 62 as a fulcrum.
This is a mechanism that cuts the sheet by sandwiching it.

The dimension L1 shown in FIG.
The dimension h is a necessary distance between the upper blade 61 and the lower blade 63 when the slide base 12 stops moving horizontally, which is a stroke when the lower blade 63 swings (moves in the direction of ⇔) with the fulcrum 2 as a fulcrum. This is equivalent to the conventional case (FIG. 10).

The feature of the present invention is that the shape of the lower blade 63 is a convex shape (hatched area) as shown in FIG. As shown in FIG. 10, the shape of the conventional lower blade 73 is a shape in which the front (axis 72) side is higher (hatched area), as is the case with office scissors that are commonly seen. In addition, when cutting the cutting target, the sharpness is improved by giving the blade a certain degree of inclination.

As described above, in the conventional shape of the lower blade 73, the front (shaft 72) side is inclined and higher, so that the portion comes into contact with the tape debris quickly.

Therefore, in the present invention, as described above, the lower blade 6
Each of the three shapes is a convex shape having a predetermined angle (also referred to as a shear angle) inclined toward both ends with the center part as a boundary, so that the contact timing with the tape waste can be delayed. Thereby, the opening and closing movement of the cutter can be made slower than in the past.

Although not shown, the lower blade 63
As another shape, for example, only the cutting edge portion on the shaft 62 side may be partially cut away, and by lowering the cutting edge portion of at least the portion that first contacts the tape scrap,
The above object can be realized.

FIG. 7 shows the cutter mechanism 60 according to the present invention.
Horizontal movement of the slide base 12 and the cutter mechanism 6
FIG. 6 is a diagram for explaining an overlapping state of the tape cutting operation by the tape cutter 0. Referring to the diagram for explaining the opening and closing operation of the cutter blade shown in FIG. 5, first, FIG.
Indicates that the cutter blade (lower blade 63) is at the initial position (opening operation)
In this state, the slide base 12 is in the middle of horizontal movement to the component supply position (region I in FIG. 7).

Next, FIG. 5B shows a cutter blade (lower blade 6).
3) shows a state of swinging (stroke L2) by a predetermined amount,
At this time, the horizontal movement of the slide base 12 is stopped, and the desired cassette tape 13 mounted on the slide base 12 is positioned at the component supply position (point II in FIG. 7).
In this case, a necessary interval (dimension h) is secured between the upper blade 61 and the lower blade 63 at this time.

FIG. 5C shows a cutter blade (lower blade 6).
3) shows a state in which the entire stroke L1 has swung, and the tape waste of the cassette tape 13 is cut by a cutter blade (region III in FIG. 7).

Then, although not shown, the cutter blade is opened again, and after the cutter blade is opened by a predetermined amount (dimension h), the horizontal movement of the slide base 12 is started.

Further, in the present embodiment, for convenience of explanation, the tape scrap to be cut has been described as if it is a tape scrap coming out of only one cassette tape 13 that has reached the component supply position. However, the present invention is not limited to this. Not something
It may be one that cuts both the desired cassette tape 13 that has arrived at the component supply position and the tape scraps coming from a plurality of adjacent cassette tapes 13. In this case, a blade that can cut a plurality of tape scraps is naturally used. Size is required. In this embodiment, among the tapes to be handled as shown in FIG. 6, a tape having a blade size that can correspond to the maximum tape width is used. Will be possible.

Further, the cutter blade of the present invention has a structure shown in FIG.
As shown in (a) and (b), an inclination is given at a predetermined angle toward both ends with the boundary substantially at the center. This is to improve the sharpness of the cutter blade, and verification has shown that cutting is best performed when the blade tip is abutted against the cutting target (in this case, tape waste) at an inclination of about 10 degrees. Was. Therefore, in the present embodiment, an inclination of about 10 degrees is provided around a substantially central portion (see inclination angles θ1, θ2, θ3 in FIG. 6).

By forming a tapered portion at the tip of the upper blade 61, the distance between the upper blade 61 and the lower blade 63 is widened (compared to the case where the upper blade is straight) and the lower portion of the cutter An appropriate angle θ3 at the blade tip can be obtained.

As described above, the slide base 12
When the horizontal blade stops moving horizontally, the lower blade is swung by the same stroke (dimension L1) in order to secure a necessary interval h between the upper blade 61 and the lower blade 63, and the tape dust is hit. The timing of contact is delayed (the swing stroke of the lower blade 63 extends from L3 to L2 (> L3) until it comes into contact with the tape waste). It is not necessary to perform this operation, and it is possible to suppress the problem that the vibration and the sound when the cutter is opened and closed are increased.

Hereinafter, another embodiment of the present invention will be described with reference to the drawings. Note that the same components are denoted by the same reference numerals, and description thereof will be simplified.

First, the feature of the second embodiment shown in FIG. 8 is that the shape of the lower blade 63 (shown in FIG. 5 and the like) of the first embodiment (that is, toward the both ends with the center portion as a boundary). Instead of the convex shape having a predetermined angle of inclination), a lower blade 63A having a concave shape (hatched area) having a predetermined angle of inclination toward both ends with respect to a center portion thereof is provided. . By adopting such a lower blade shape, as in the first embodiment, it is possible to delay the timing of contact with the tape debris as compared with the conventional cutter lower blade 73, and the cutter can be compared with the conventional cutter lower blade 73. Opening and closing movement can be slowed down.

Since the lower blade is formed in a concave shape which is inclined at a predetermined angle with the boundary substantially at the center, the sharpness when cutting the tape waste is improved as in the first embodiment. It is also possible to handle a plurality of tape scraps.

A feature of the third embodiment shown in FIG. 9 is that tape scraps are cut by vertically moving (sliding) the lower blade 63B of the convex shape toward the upper blade 61. . Note that the lower blade 63B is not limited to the convex shape, and may be, for example, a concave shape.

Referring to FIG. 9, the cutter mechanism 60A will be described. An oscillating body 65 having one end fitted to the lower blade 63B (for example, linked by a cam follower 64).
By pivoting the other end of the lower blade 63B (shown by a dashed line in FIG. 9) in the direction of the arrow (⇔), the lower blade 63B moves to the lower blade upper and lower guide 67 which is vertically movable on the lower blade guide 66. While being guided, it is moved in the direction of the upper blade 61 to cut the tape waste. Note that the dimension L11 shown in FIG.
Dimension L12 is a stroke up to a necessary interval (dimension h) between the upper blade 61 and the lower blade 63B when the slide base 12 stops moving horizontally. Therefore, the shape of the lower blade 63B is designed so that the dimension L12 is longer.

As an effect of this embodiment, as in the first and second embodiments, the timing of contact with the tape waste can be delayed, and the cutter blade needs to be opened and closed at a high speed as in the prior art. As a result, vibration and noise during the opening and closing operations can be reduced. In addition, by making the lower blade shape a convex or concave shape that is inclined at a predetermined angle around the center, the sharpness when cutting tape waste is improved, and multiple tape debris can be removed. It becomes available. More importantly, in the first and second embodiments, when cutting the plurality of tape scraps and the wide tape scraps, the lower blade itself cuts the tape scraping while swinging. In the embodiment, since the lower blade 63B cuts the tape waste while keeping the designed blade shape, there is an effect that the cutting workability is good. In addition, the shear angle can be set to an optimum constant angle at any cutting position, and the optimum sharpness can be obtained at any position. Further, the cutting is performed with the same force at any cutting position, and the load on the driving source can be kept constant.

The present invention is particularly effective when applied to a machine in which the horizontal movement of the slide base 12 and the cutting operation by the cutter are overlapped.

[0059]

According to the electronic component supply device of the present invention,
The component base on which a large number of component supply units are mounted is moved, the electronic components stored in the tape in the desired component supply unit are supplied to the component supply position, and the component supply unit reaches the component supply position by the horizontal movement of the unit base. The lower blade of the cutter mechanism that cuts the tape scraps after the electronic components have already been taken out swings about the one axis as the fulcrum toward the upper blade side,
And in the horizontal movement of the unit base and the cutting operation of the cutter mechanism are overlapped,
Since the lower blade has a convex or concave shape, the timing at which the lower blade comes into contact with the tape debris when swinging can be delayed. Therefore, it is not necessary to perform the high-speed opening and closing operation of the cutter blade as in the related art, and it is possible to reduce vibration and noise during the opening and closing operation.

Further, by forming the lower blade into a convex or concave shape which is inclined at a predetermined angle with a boundary substantially at the center, the sharpness when cutting the tape waste is improved, and a plurality of tapes are cut. It becomes possible to deal with waste.

Further, by making the lower blade shape such that the blade portion on the shaft side serving as a pivot point is cut out, the timing of contact with the tape waste can be delayed, and the cutter blade can be moved at a high speed as in the conventional case. It is not necessary to perform the opening and closing operation, and the vibration and sound during the opening and closing operation can be reduced.

By moving the lower blade of the convex or concave shape up and down (sliding) in the direction of the upper blade, the lower blade is lower than the one that cuts the tape debris while swinging. Since the tape scraps are cut while abutting against the tape scraps while keeping the designed blade shape, the cutting workability is good. In addition, the shear angle can be set to an optimum constant angle at any cutting position, and the optimum sharpness can be obtained at any position. In addition, all the cutting positions are cut with the same force, and the load on the drive source is reduced. Can be constant.
